Abstract

Abstract Spin relaxation rates of protons in hydrides of LaNi 5−xCu x (1⩽ x ⩽ 5) were measured in the temperature range 170 K⩽ T ⩽ 400 K. The temperature dependence of T 2 yields a diffusional activation energy E a which increases nearly monotonically from LaNi 4CuH 4.7 to LaCu 5H 1.5. The spinlattice relaxation time T 1 does not exhibit a clear minimum in T 1 versus 1/T plots, as found previously for LaNi 5H 6. We point out a possible correlation between the behaviour of E a and the hydrogen thermodynamic properties of these hydrides.
